Trace Logs
In addition to the syslog buffer, Dell Networking OS buffers trace messages which are continuously written by various Dell
Networking OS software tasks to report hardware and software events and status information.
Each trace message provides the date, time, and name of the Dell Networking OS process. All messages are stored in a ring buffer.
You can save the messages to a file either manually or automatically after failover.
Auto Save on Crash or Rollover
Exception information for MASTER or standby units is stored in the flash:/TRACE_LOG_DIR directory. This directory contains files
that save trace information when there has been a task crash or timeout.
•
On a MASTER unit, you can reach the TRACE_LOG_DIR files by FTP or by using the show file command from the flash://
TRACE_LOG_DIR directory.
•
On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command from the flash://
TRACE_LOG_DIR directory.
NOTE: Non-management member units do not support this functionality.
Last Restart Reason
If the system restarts for some reason (automatically or manually), the show system command output includes the reason for the
restart.
The following table shows the reasons displayed in the output and their corresponding causes.
Table 109. Line Card Restart Causes and Reasons
Causes
Remote power cycle of the chassis
reload
reboot after a crash
Hardware Watchdog Timer
The hardware watchdog command automatically reboots an Dell Networking OS switch/router with a single RPM that is
unresponsive.
This is a last resort mechanism intended to prevent a manual power cycle.
